Currently, the two target dates most commonly cited for achieving zero greenhouse gas emissions are 2050 and 2100. Given the extreme weather weirding we are witnessing at current levels of pollution, we shudder to think what 35 years—let alone 85 years—of continued emissions will bring. Everyone can see that the climate is already on steroids and wreaking havoc.

The urgency of our planetary emergency requires that we transition from fossil fuels to renewables not in decades, but in years. We must move beyond what conventional wisdom views as politically feasible to what this existential crisis truly demands: an all hands on deck societal mobilization at wartime speed.

To be clear, we are not suggesting ending the use of fossil fuels tomorrow. Decarbonizing our industries, homes, transportation, power generation and food production will take time, probably longer than 2020. Let’s hope it doesn’t take us until 2030. But we must make this transition as quickly as humanly possible.

In 2011, an unprecedented coalition of planetary protection leaders called on the presidents of the U.S. and China to declare a global climate emergency by launching a wartime-like mobilization to cut carbon emissions 80 percent by 2020. Because that urgent call was not heeded, we have lost precious time in the race to save civilization, and must now set our sights even higher.

To this end, we join with our allies at The Climate Mobilization in calling on Congress and the White House to revitalize our economy and put America back to work by declaring a U.S. goal of net zero greenhouse gas emissions by 2025.

Some will no doubt call this bold national goal unrealistic, but they would underestimate the innovative genius and social conscience of the American people. America has a long and proud history of overcoming seemingly insurmountable odds (consider World War II, Apollo program and Abolitionist movement). What is unrealistic is thinking we can put off for decades action that is desperately needed now to ensure our survival as a species.

We will be reminded of the fragility of our existence this summer when the victims of Hurricane Katrina are honored on the 10th anniversary of that savage storm. We will be reminded again this fall when the victims of Hurricane Sandy are commemorated on the third anniversary of that superstorm’s lethal landfall.

Five months from today, delegates from more than 190 nations will gather in Paris for the 21st UN Convention on Climate Change (COP21) to negotiate a global climate accord—this after decades of failed international talks have only watched fossil fuel emissions continue to soar. For the sake of all that we love, we cannot allow COP21 to become yet another climate cop-out.

Intergenerational justice demands that the centerpiece of the Paris agreement be zero emissions, a goal UN Secretary-General Ban Ki-moon calls “ambitious but achievable.” Five months is ample time for the nations of the world to draft their legally binding zero emissions commitments for Paris.

In his widely anticipated encyclical, timed to influence the Paris talks, Pope Francis writes, “Reducing greenhouse gases requires honesty, courage and responsibility, above all on the part of those countries which are more powerful and pollute the most.” As the nation that historically contributed the most to global climate pollution, and that is in the strongest position to respond, the U.S. has a moral imperative to lead the zero emissions charge at COP21.

PAUSE is a grassroots group of individuals who have come together to promote safe, sustainable energy and fight for environmental justice. We engage the greater public to stop the fossil fuel industry’s assault on the people of Albany and our environment.
